Danger warning signs (P-1–P-50)

They tell you a hazard that is hard to spot in time is coming up, and what kind it is, so you can adjust your driving.

How to recognise them: An equilateral triangle pointing up, with a red border and a white background carrying a black symbol.

How this group is laid out

The definitions in this group nearly always follow one pattern, "danger from the approach of…", and what changes is the ending: a junction, a bend, a level crossing, a stretch with loose animals, or chippings thrown up by passing vehicles. The codes group the warnings by stem. The P-1 signs announce a junction whose users must give way: the letters a to d say where that road comes in from, and P-1e warns of a stretch with several direct accesses. P-2 warns of the opposite, a junction where the general priority rule applies. The regulation also counts some of them as priority signs while they remain danger signs: P-1 and P-1a to P-1d, P-2, P-6 for trams, and P-7 and P-8 for level crossings.

Level crossings have a series of their own. P-7 and P-8 separate crossings with barriers from those without, P-11 marks an unbarriered crossing immediately ahead, and the P-9 (right-hand) and P-10 (left-hand) markers count down the distance; P-9a and P-10a always come with a P-5, P-7, P-8 or P-27. Other letters only change the side, as with the P-13 and P-14 bends, or narrow down the hazard, as with P-24a, where a large share of the wild animals are wild boar. For anything no other sign describes, there is P-50.

How to tell them apart

Signs in this group that look alike, and what separates them according to their definitions.

P-1 P-2
At P-1, traffic coming from the other road must give way. At P-2 neither road has priority and the general priority rule applies. Both are danger signs, and the regulation counts both as priority signs too.
P-7 P-8 P-11 P-11a
P-7 announces a level crossing with barriers or half-barriers, and P-8 one without. P-11 no longer announces anything: it marks an unbarriered crossing right there, and P-11a adds that it crosses more than one railway track.
P-9a P-9c P-10a
P-9 markers stand on the right of the carriageway and P-10 markers on the left. In both series, letter a is furthest from the level crossing, opening bridge or quay and c is closest; the a marker always comes with its danger sign.
P-15 P-15a P-15b
P-15 is the general one: it warns of a hump, a dip or a badly surfaced road. P-15a says that what is coming is a hump, and P-15b that it is a dip.
P-20a P-20b P-20c
P-20a warns of one or more pedestrian crossings; P-20b of a place or stretch with heavy pedestrian traffic. P-20c is a pedestrian crossing alongside, or shared with, a cycle crossing.
P-23 P-24 P-24a
P-23 warns of domestic animals or livestock that often cross the road; P-24 of wild animals. P-24a is the same warning where a very significant share of those animals are wild boar.
